METAL RooFlNG.

SPECIFIGAELION forming part of Letters Patent No. 237,133, datedFebruary 1, 18,81.

Application tiled September 15, 1880. (No model.)

To all whom it may concern:

Be it known that I, L Lnwrs SAGENDORPH, acitizen oftheUnited States,residing at Staunton, in the county of Augusta and State ofVirginia,have invented certain new and useful Improvements in MetalRoofing; and I do hereby declare the followin gto be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or fi gures ofreference marked thereon, which form a part of this specication.

Figure l is a perspective view of a single sheet from a number. of whichthe rooting is formed; Fig..2 is a perspective view of one of the cleatsfor securing the sheets together and to the sheathing. Fig.3 is avertical crosssection of two of the sheets united, showing the cleatnailed to the sheathing, but not bent up over the cap 5 and Fig. 4 is across-sectional view, showing two of the sheets united to form the seam,the cleats nailed to the sheathing, bent up over the cap, and the seamcompressed as it appears in use upon the roof. Fig.5 is a sectionaldetail of the laying seam, and Figs. 6 and 7 are moditicationsof thestandin g seam.

The invention has relation to metal roofing; and it consists in theimprovements in the construction of the same hereinafter fullydescribed, and particularly pointed out in the claim.

In the accompanying drawings like letters ot'reference indicatecorresponding parts in the several igures.

Heretofore great difticulty'has been experienced in constructing thestanding seam of metal rooting to avoid the breakage resulting from thecontraction and expansion caused by heat and cold upon the metal sheetsof which the roof has been composed. Rivets, eyelets, staples,indentations, and the like have been employed to secure the standingseam; but they are all open to the same objection-viz., the contractionA and expansion of the metal will cause them eventually to break or tearloose and permit leakage at the seam. My object is to provide a standingseam for metal roofing that will not be open to this objection, and Iwill now proceed to describe in detail its construction.

A designates one of the metal sheets of which theroof is to be formed,provided at one side with a single upturned vertical ange,B,hav ing aseries of slots, C, formed therein, and at the opposite side with adouble flan ge, D,forrned by drst bending the edge of the sheet up andthen bending the single lian ge thusformed outwardly and down to form aninverted U, one arm ofwhich,however, is shorter than the other, as shownin the drawings. In the curve ofthe inverted-U ange is placed a packing,a, of felt@ er, or red lead, or any other suitable 'material tha -wllexclude Water and save the meta-l from breaking when the standing seamis being compressed or hammered. Felt, however, is preferable forconveniently handling. This packingtakes the place of solderindoubleseaming and prevents the roof from rattling, as it acts as aninsulator. I also place the packing between all the joints of the roof,the' cross-seams, standing and hooked seams. By using the packing thefire-pot is unnecessary, and the danger ot' re to the building whilerooting it is removed. Besides, the packing will not break as solderdoes, and the durability of the roof is increased.

The slots C may be either round or oval, or

as shown iu the drawings, and may be made with a punch or knife, or inany other suitable manner.

I intend in practice to make the sheets by machinery, although, as isobvious, they may be readily made by hand.

E designates the cleats,which are also of sheet metal,andwhich are to bepassed through-that is, inserted in-the slots C in the. single flange B.The ends of the cleats E, that project from the outside of the flange B,are to be bent down, as shown, and secured by the nails or screws F,driven through the holes G punched in them, to the sheathin gH. Theother ends of the cleats E, which are the longer ends, are bent downupon the inside of the flange B, as shown. The double lange D ot'another sheet, A, is then placed over the flange C and the cleats E andpressed down to place, and the ends ofthe cleats E,which now projectfrom beneath the double flange D, are then bent up and back over the topof the double llange D, and then down againstits side, as shown in thedrawings. A seamer is then used to compress the several parts tightlytogether to exclude water. By this construction each sheet contracts andex- IOO pands independently of the other, as also do the cleats, so thatno strain comes upon the seam or the metal of which it is formed, andthe seam cannot therefore break or tear loose, as iu the constructionshereinbefore referred to.

From the foregoing description, taken in connection with the drawings,the construction and operation of the device will be readily understood.

Itis practical, simple, durable, and may be cheaplyconstructed, andpossesses advantages not heretofore attained.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

In testimony whereof I affix my signature z5 in presence of twoWitnesses.
